    Can you post the log of this happening?

    If everything else stock? Like air intake, exhaust headers, fuel injectors?

    The fuel injector flow rate doesn't look factory anymore.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    thank you for the reply 5FDP, i got the car like this, intake stock exhaust stock, injectos looks stock but i never took them out to see, the engine does rev up normal sometime. is there anything i can start to look for ? is this something to do with fuel pump ? could this be a MAF related problem? or maybe the gas padle?
    thank you very much.
